a HYDRAU IIC EAS Q I To all whom it may concern:

Be it known that we, (1) ALEXANDER Cznnnrmnsxr and (2) JOHN BARAN, 1) a subject of the Czar of Russia and a citizen of the United States of America, residing at Buffalo, in the county of Erie and State of New York, have invented cer tain new and useful Improvementsin I-Iy-' clraulic Fans, of which the following isa specification.

This invention relates to certain new and useful improvements in hydraulic fans.

An object of the invention is to provide a hydraulic fan in which a casing is so constructed as to house a water motor and to carry a projecting shaft extending through.

the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be hereinafter more fully described and then claimed. In the accompanying drawing which shows the preferred embodiment of the present invention and to which reference is had herein by like characters designating corresponding parts throughout the several views :Figure 1 is a vertical longitudinal sectional view. Fig. 2 is a vertical cross sectional view taken on line IIII of Fig. 1, and Fig. 3 is a horizontal sectional view taken on line TIL-III of Fig. 1.

Referring more in detail to the accompanying drawing, the reference numeral 10 designates the rear wall or main body portion of the water motor housing which is preferably of the shape shown in Fig. 1 to provide a reduced lower portion that may constitute a hand-hold and an enlarged continuously curved upper portion. v

The main body portion 10 adjacent its upper end is provided with a circular recess or depression 11 while the neck portion of the member 10 is provided with a pair of fluid conducting passageways 12 and 13,

the passageway 12 affording an inlet for the Specification of Letters Patent. Patented Feb. 8, 1916.

13 a ords an outlettherefoigthelower ends ofthe passageways 12 and 13 being provided :wi'th outleti openings 14 and. 15 re spectively and having a' closed front wall 16 as clearlyindicated in :Figs. 2 and 8. The central body portion 17 constituting the separating partition for thepassageways 12 19 from the passageway 12int0 the re-' cess 11. An opening 20 affords communicatlon between the recess 11 and theoutlet passage 13, which passage 13 as before stated, communicated with the outlet opening 15. A water motor i s'mounted within the recess 11 and includes the central body portion 21 carrying radial blades 22 that wlpe the side wall of the cylindrical recess 11, while a stub shaft 22 is carried by the body portlon 21 and extends through the rear wall 10 of the device'to constitute a suitable ournal bearing. A removable front wall 24 is secured to the front wall of the body portion 10 asbysuitable fastening members 25 and carries at its lower end an integral boss 26 provided with an opening 27 that-registers with the inlet opening 14 anda second opening 28 that registers with the outlet opening 15, both of which openings in the boss 26 are internally screw-,

threaded to adapt the same for the reception of plpes or other fluid conducting members n opening is provided adjacentthe upper end and centrally of the front wall 24 through which extends the shaft 30 carried by the water motor 21 and mounted on said extended shaft 30 is a fan blower 31 detachably connected thereto as by a fastening screw" 32. The inlet opening 12 is of cross sectional area reduced relative to the outlet passageway 13 so that the pres sure in theinlet will be increased and therefore provide greater power for the water motor 21.

From the above description, it is believed repelling. fluid, while the passageway vanes carried by the hub adapted to wipe the end wall of the recess, inlet and outlet passage-ways formed in the body-portion below the recess and communicating therewith, the inlet passageway extending to the upper end of the body-portion and communicating with the recess at that point, there being inlet and outlet openings in the lower end of the body-portion communicating with the inlet and outlet passageways, and a removable front wall for the body-portion having openings therein communicating with the inlet and outlet openings of the body-portion.

In testimony whereof we affix our signatures in presence of two witnesses.
